Product introduction

The HCDB series submersible hydrostatic level gauge is based on the principle that the static pressure of the measured liquid is proportional to the height of the liquid. It uses a pressure sensor to convert the pressure signal into an electrical signal, which is then converted into a standard current signal or digital signal after temperature compensation and linear calibration. Signal.

Use imported high-quality silicon piezoresistive sensors or imported high-quality ceramic sensors; gas cable structure; reliable sealing technology, superior stability, reliable modular design, strong applicability; with analog and digital RS485 ; Widely suitable for liquid level measurement in various fields and industries.

External structure

Features

1. Use high-quality cables with air ducts and can be equipped with on-site displays.

2. Two sensing modes are available, and the sensor has a large hole design for various application working conditions, preventing clogging and corrosion.

3. Using imported silicon piezoresistive sensor, it has high precision and good stability.

4. Directly put into the liquid to be measured, easy to install.

Installation and maintenance

Note: The die-cast aluminum housing cannot be installed upside down!

1. Pay attention to the installation position during installation, and the cable fixing head must be locked and ensure that the cable at the connection port is lower than the connection port to prevent rainwater from penetrating into the junction box through the outlet when it rains and damaging the internal structure and wiring.

2. When the HCDB series liquid level meter is used for a long time in non-clean water, sedimentation substances may block the probe and affect the normal operation of the sensor. At this time, cleaning measures need to be taken. First, remove the probe part of the liquid level gauge from the liquid being measured and wipe it clean.

3. Warning! The equipment can only be installed when there is no power supply! Wire the equipment according to the technical parameters, signal line definitions and wiring diagrams shown in the instructions.

4. Users must ensure that the outer diameter of all cables is within the allowable range of the gland. In addition, make sure that the cable is installed firmly and without gaps in the sealing ring of the gland.
